I tried to avoid Josy as much as possible since day 1, after she told me she's in a relationship. So I'm forced against my will to go on a date with her when I went home for a weekend, but OK, I accept that. I didn't do anything else with her, since she hasn't solved her situation yet. By then I was pursuing Maya so I can understand she becoming attached to me, and I can understand Josy's feeling something for me too even if I don't want anything with her, because I'm being nice and supportive and all. Then Josy comes to the dorm and we discover their relationship. At this point MC storms out of the room. If I'm not mistaken, I don't meet them again (appart from casual and logical encounters at the school) until DIK's party when we have that conversation at the DIK's library. I choose to be friends, they are OK with that. We won't meet again until prep's party, we share a friendly talk and Josy tells us her dad is coming.
As a friend who may have play a part on all that mess with her father, I agree to go with her, hoping I will be able to explain myself and tell her dad that nothing happened between us on that night. But this is not neccesary as the man is there just to fix things with her daughter. Nice. I escort her to the dorm like a friend would do and then she tells me out of the blue that she'd only agreed to a friendship because she felt forced to do so, and my MC, who is acting just as a supportive friend (what DPC has allowed us to be, a position I'm happy with) starts to consider his feelings for her. NO! At this point I don't have any romantic feelings for her. I'm forced to feel that way. And if I choose to stay with Maya instead of helping Josy with her father, she more or less says something similar.
And after that I don't get any more scenes with them (I can't recall where did I sleep that night, but I'm sure nothing funny happens with any of them, and of course I don't get the picnic scene). But I'm sure my MC haven't ruled out any romantic relationship with them (at least with the one I choose to stay with when Josy's dad came to the party), and that's frustrating because I really want to do so.
I really hope you are right
Edit - TL;DR: My point is that, even when we decide to be just friends, we end this chapter suspecting that decission is not being taken into account. Maybe in the future we'll see a clear friendship path thanks to that decision but as for now we don't, and that's not a sign of 'good game-writting'. Some minor variations on the script would have been enough to avoid this frustrating feeling, but they just aren't there
